The guy has probably never heard of the Seiko Spring Drive, where the hands are moved by a spring and regulated by a brake. Therefore they're completely smooth.

  It's a bummer that video plays at 30fps. This is a case where 60 (does YouTube do higher framerates?) would pay off.

  Spring Drives are pretty rare outside of Japan. Most mechanical watches today tick 8 times a second. On a small watch it's pretty smooth to me.

    The balance wheel oscillates at 8 beats per second, but it requires 2 beats to complete a full second "tick", so most modern mechanical watches actually tick at 4 times per second. http://en.wikipedia.org/wiki/Balance_wheel#Period_of_oscillation http://en.wikipedia.org/wiki/Balance_wheel#Period_of_oscilla...

      It is 8 ticks per second. Look at this video of the hand up close (it's a 28800 bph movement): https://www.youtube.com/watch?v=FxgahvNH3q0 https://www.youtube.com/watch?v=FxgahvNH3q0
